Growth and characterization of organic NLO material: Clobetasol propionate

•A organic crystal clobetasol propionate has been grown with size up to 6 × 4 × 3 mm3.•It emits green radiation at 532 nm.•It is thermally stable up to 195 °C.•Photoluminescence observed at 421 nm indicates the blue emission.

Single crystals of clobetasol propionate (CP) have been grown by slow evaporation solution technique using mixed solvent of methanol–acetone. The grown crystals were subjected to single crystal X-ray diffraction analysis to confirm their lattice parameter and space group. The powder X-ray diffraction pattern of the grown CP has been indexed. Thermal analysis was performed to study the thermal stability of the grown crystals. Photoluminescence spectrum shows broad emission peak observed at 421 nm. Nonlinear optical studies were carried out for the grown crystal and second harmonic generation (SHG) efficiency was found in the crystal.
